Abstract
An image reading apparatus includes a platen on which a document is to be placed; an image generating unit that performs scanning on the platen to generate a position detection image and an output image; a document position detecting unit that detects whether a document exists and a position of the document based on the generated position detection image; a document extracting unit that extract an area corresponding to the document from the generated output image; and a control unit that controls the image generating unit, the document position detecting unit, and the document extracting unit so as to output an image of the extracted document.
Claims6
An image reading apparatus comprising:
- a platen on which a document is to be placed;
- an image generating unit that performs scanning on the platen to generate a position detection image and an output image;
- a document position detecting unit that detects whether a document exists and a position of the document based on the generated position detection image;
- a document extracting unit that extract an area corresponding to the document from the generated output image;
- and
- a control unit that controls the image generating unit, the document position detecting unit, and the document extracting unit so as to output an image of the extracted document.
An image reading method causing a computer to perform:
- generating a position detection image and an output image by performing scanning on a platen on which a document is placed;
- detecting whether a document exists and a position of the document based on the generated position detection image;
- extracting an area corresponding to the document from the generated output image;
- and
- outputting an image of the extracted document.

- a document position detecting unit that detects whether a document exists and a position of the document based on the generated position detection image;
- an image converting unit that extracts an area corresponding to the position from the generated position detection image to convert the area into an image to be output;
- and
- a control unit that controls the image generating unit, the document position detecting unit, and the image converting unit so as to output the converted image.
